Previous studies on this, which considered only local shrinkage, produced large errors in the calculation of thick and large curvature plates because the whole deformation was ignored. In this article, new mathematical formulas are proposed...

They first calculated the lines of curvature of a prescribed surface and evaluated the points of extreme principal curvatures along the lines. They then classified and grouped those points based on their principal directions...

..., the heat input of the metal near the plate edge is less than that of the internal metal along the heating line due to the decrease of heat power near the plate edge, thus causing smaller transverse shrinkage of the plate edge. To solve this problem, the paper investigates the suitable heating way...
